vue-star評星組件開發執行個體，vue-star執行個體

star檔案夾下建立Star.vue，及相關的圖片資訊。便於組件的就近維護

Star.vue：

<template> <div class="star" :class="starSize"> <span v-for="(itemClass,key) in itemClasses" :class="itemClass" class="star-item"></span> </div></template><script> const LENGTH = 5; const CLS_ON = 'on'; const CLS_HALF = 'half'; const CLS_OFF = 'off'; export default{ props:{  size:{ //尺寸，24,36,48  type: Number  },  score:{  type: Number  } }, computed:{  starSize(){  return 'star-'+ this.size;  },  itemClasses(){  let result = [];  let score = Math.floor(this.score*2)/2; //將數值調整為整數及.5的形式，例：4.3 => 4；4.6 => 4.5  let hasDecimal = score %1 !==0;  let integer = Math.floor(score);  for(let i =0;i<integer;i++){   result.push(CLS_ON);  }  if(hasDecimal){   result.push(CLS_HALF);  }  while(result.length<LENGTH){   result.push(CLS_OFF);  }  return result;  } } }</script><style lang="stylus" rel="stylesheet/stylus">@import "../../common/stylus/mixin.styl";.star font-size: 0 .star-item display: inline-block background-repeat: no-repeat &.star-48 .star-item  width: 20px  height: 20px  margin-right: 22px  background-size: 20px 20px  &.last-child  margin-right: 0  &.on  bg-image('star48_on')  &.half  bg-image('star48_half')  &.off  bg-image('star48_off') &.star-36 .star-item  width: 15px  height: 15px  margin-right: 6px  background-size: 15px 15px  &.last-child  margin-right: 0  &.on  bg-image('star36_on')  &.half  bg-image('star36_half')  &.off  bg-image('star36_off') &.star-24 .star-item  width: 10px  height: 10px  margin-right: 3px  background-size: 10px 10px  &.last-child  margin-right: 0  &.on  bg-image('star24_on')  &.half  bg-image('star24_half')  &.off  bg-image('star24_off')</style>

Header.vue：

<star :size="48" :score="3.5"></star><script>import star from '../star/Star.vue'export default{ components:{ star }}</script>

mixin.styl：

bg-image($url) background-image: url($url + '@2x.png') @media (-webkit-min-device-pixel-ratio: 3),(min-device-pixel-ratio:3) background-image: url($url + '@3x.png')
